I got these from Summit back in the winter, so it's fairly recent. They look the same as the ones on their website (AMD) now. There's a HRM article online about replacing these on a 70 GTX. They saved the inner houses and just cut the outers off leaving the original flange and spotwelds. This replacement from AMD was then welded to the outside of the inner panel on the front side instead of being welded to the inner like original. I wish the pics in that article were better so I could see exactly what he did!
